Hey Folks, Right now i'm trying to fix a problem i got with an Interrupt Service Routine created by ProcessorExpert and CodeWarrior: The ISR loses received chars (as in not calling the appropriate Event Handler) when the reception of that char is finished while the transmit-ISR is running. As far as i can tell, this happens because the transmit-ISR clears a status register which also co...

Hi, to ease the routing of my PCB, I'd like to swap some data lines on a SDRAM. I'd like to be 100% sure that the swapping will not create problems once the PCB is built. I use a SDRAM MT48LC8M16A2 from Micron. The only documentation that I found is: http://www.freescale.com/files/32bit/doc/app_note/AN2582.pdf about DDR, and they say "Pin-swap within a given byte lane to optimize the...

I have a Freescale MPC5200 board I designed a while ago which comes out of reset (I am writing the flash with a debug monitor which has served me over the years - I wrote it first for the 68020, then I made a CPU32 version, then an MPC8240 version etc...), and the monitor says something through the UART (I use PSC_6). But the baud rate is totally off the mark. I made the other system ...

Just when you thought OTP was a thing of the past, someone shakes things up. http://www.eeproductcenter.com/micro/brief/showArticle.jhtml?articleID=197800244 http://www.silabs.com/public/documents/pr_doc/products/Microcontrollers/Small_Form_Factor/en/T60 0_FINAL.pdf Looks likely to shake up Microchip and Freescale ? Wonder how they test these ? -jg

sci.electronics.design single axis analog gyro Freescale & ST Micro seem to be getting out of the analog gyro business and going to digital "system" types of devices. Analog Devices are too costly for this application, ie ~$35. A single axis analog gyro with 3,4, maybe 10 mv per degree/second at $2-$3 in 100's is the current objective. Ivensense Inc appears to have just that,...

Hi, I try to use a FREESCALE MC13213 (ZigBee) in single port mode. I generated a CodeWarrior project with BeeKit for a NCB board (not mine ; I use a custom board). I read the AN3248 and changed the value of the 0x07 modem register (0x5C00 instead of 0x4C00). My board doesn't receive or transmit anything (the same code is running well on 13192EVB and SARD board on the same time). A...

I'm playing with the MPR121 touch sensor controller demo kit from Freescale... and it works :-) Now I want to assembly a complete capacitive touch keypad that can be seen without ambient light, so I'm trying to find a solution for backlighting. The keypad should have three layers: the PCB with capacitive pads, a transparent sheet with a diffuse light and a opaque label with transpare...

Hello, Maybe someone's seen something like this and can shed some light on the problem. This is a Power PC (83xx) using the Ethernet driver Freescale provides on the BSP ISO image. 100Mb works fine sending and receiving packets (lwIP is up and running well). Gb initializes fine but won't send or receive packets. The driver sends the packet without error, the jack and switch lights...

Hi, I'm debugging the p2020 based system. When building the u-boot loader, it is essential to provide good DDR parameters in the boot_format configuration file. Unfortunately I can't find any description of those parameters neither in http://cache.freescale.com/files/32bit/doc/app_note/AN3659.pdf nor in p2020 manuals. Does anybody know where those parameters are described and how to suit...

Good afternoon: I need to perform some unit testing and I'm totally lost. Right now I'm working in two projects. In the first one I use a Freescale MC908AS60A microcontroller with Cosmic compiler and the other one a Infineon XC161 with Tasking C166 compiler. The manager is asking me to perform Unit testing on host and on target. I have been able to perform some testings on host, but I ne...

Hi, I'm using CodeWarrior for 56800/E Special Edition v7.2 and a parallel port JTAG command converter. For some reason, programming the 56f8322 flash with CW does not work. With CCS server running, CW connects fine and without complaints over the JTAG adapter, and shows sensible hex/asm uploaded data for the compiled source, but a P mem dump returns 0xFFFF's and a P mem fill with e.g....

Hi all, I am planning to develop an embedded application with the Freescale (Motorola) MC9S12DP256 microcontroller. I aleready have a good 10 year knowledge of HC11/HC12 C/assembly programming, and electronics design, what I need now is a good development kit, including compiler and Backgroud Debug Mode. Question # 1 So what kit should I buy to start with ? I saw IAR Embedded Workbenc...

last 2 days I was at a customers machine searching for bugs without any success. CPU ist a Freescale 6808 and code written in assembly (by me about 5 years ago). The machine is now in production for about 1,5 years. In that time about 10 million pcs have been produced with. The upper unit consists of a turn table with 2 opposite mounted grabbers. The lower unit consists of a shuttle for fe...

Hi all, I just started to develop Linux OS for arm920t processor. I want to build very simple and quick kernel, because I need real-time operations. I have compiled 2.6.23 kernel (XIP, 1.1MB), have wrotten simple bootloader (1.5KB). I use uClibc and buildroot toolchain. I want to start linux kernel as quick as possible after power on (less that 1s is wanted). I will disable console, will ru...

Hello. I have problem with Monitor Mode in MC68HC908GP32. I try to programme this uC so I use PROG08SZ programmer (on Windows 2003). I made Normal Monitor Mode Circuit from AN2317/D Application Note (page 9): http://www.freescale.com/files/microcontrollers/doc/app_note/AN2317.pdf but I used a 8 MHz oscillator. My GP32 connections are show below: RST -> Vdd (with pull-up resistor) IRQ

I'm looking for an embedded microprocessor that can run a web server. The purpose of it will be to configure an embedded system via a web page similar to how you configure most routers. I've been looking around and have found a few linux ports that run on the Freescale ColdFire microprocessors and the ARM microprocessors however they all are made for specific development boards. (Looked int...

Dear colleagues, I'm trying to interface Casio 3,5" TFT display (COM35T3193KTC) to Epson S1D13705 controler and Freescale MC56F8366 DSP. After a day of timing configuring everything seems to be OK but I have one big problem with display contrast and colors - it's not possible to display whole black screen. When I fill screen with white colour It's possible to display only very narrow colour bars ...
