I've been considering the idea of adopting the Freescale (a.k.a. Motorola) MPC870 processor for a board requiring ethernet, serial, USB (host and device), I2C and SPI connectivity, among other things. The processor would run FPGA-based signal processing hardware on the same board, handle configuration, firmware uploading and remote control/monitoring functions. One of the interesting thing...

Hello I want to buy a 683xx development kit, a 68302 preferrably. Can anybody tell where I can find/order/buy them online? I checked the Freescale site and found a few but they are very expensive. I am looking for a cheap kit for use in my free time. Thanks. VG

could anyone point me to a source of ideas on how to use the SCI serial port in mc9s12 parts? on the freescale site i did find a description of a monitor program AN2548.PDF (which i suppose to rely on RS-232 comm's) but, though the assembly listing is said to be available, i failed to find it on the site or elsewhere in the www does anyone know where to find AN2548SW1.ZIP? or can you poin...

Hey All, I have a header file for MPC8xx freescale powerPC QUICC I uC (MPC885 specifically). I want to write a simple code to do a simple read write for any of the INPUT/OUTPUT PORTs. I went through a documentation but I dont know how to make use of the header file to make my job easier. I am new to C/C++ so it will be great if someone can point me in the right direction. May be a small snip...

I am writing a simple SPI driver for this uC. I was wondering if someone can help me with a little bit of C code to perform a simple loopback test or point me in the right direction. "The main obstacle is I dont know how to write RBASE and TBASE in SPI PRAM to point to RxBD and TxBD in DPRAM." I am following the SPI Master programming example given in the user manual of MPC860 documenta...

I'm working with a Freescale MC9S12DG256B with MW CodeWarrior IDE in C.

I'm using the cosmic c tools version 4.4.22 (for the Freescale 9S12 MCU) and would like to be able to link MY OWN libraries to banked segments. I am thinking that if I compile the code that goes into the libraries with the +modf option, all functions will then be "far" and I can locate them in banked segments. However, I am not sure what technique to use in the linker command file (.lkf ...

HI, I have a CAN bus archeitecture and want to know if i can check the age of message or freshness of received message. Transmitter does not send any freshness bit with the data. Its receiver resposibility to check if the data is received at certain rate. ANY ideas are welcome because if stuck. I am using freescale S12 series. Thanks

Hello, I'm new to linux and I have MX31ADS board from freescale. I need to read and write to some GPIO ports and I was wondering how to do it. I dont even know which pins on the MX31 chip are available to use, how to set the port direction, or read and write to the ports from a linux C program. Does any body know where I can get some information on how to do it? maybe some sample ...

Hey folks, i got some strange problems with CodeWarrior for freescale's HCS12X family. On various occasions it complains about variable types like "uint8_t" not being defined. As far as i know, uint8_t is required by ANSI-C though as some fixed-size type. Am i plain wrong here or does codewarrior behave strange indeed?? TIA, Florian

Can anyone recommend a WLAN card for the following system: - PowerPC freescale MPC5200 (PPC 603e core) - Linux kernel 2.4.25 (www.denx.de, module linux_2_4_devel) - form factor: MiniPCI type III Until now, I have two old cards running on that platform (Hermes- and Prism-chipset). But these cards are discontinued. I have also tested a few newer cards - but without success. The Athero...

Hi to everybody! I should implement a function on my uC (Freescale MAC7121) that will receive and/or send data with length > 8 bytes: is it possible? I read on the datasheet that the message buffer is max 8 bytes, but I need to send and to receive more data.

Hi, i want to use zigbee: i know only freescale ZigBee and i'm looking for better alternatives...For me it is very important (in order): 1. Open source ZigBee stack (a stack with obfuscated source code is very difficult to use) 2. System on chip solution (micro 8bit+transceiver) (better at 868MHz) 3. to be used in very low power solution 4. low cost Any suggestion? Thanks in advance

Hi all - Perhaps some of you have encountered this? The post linked below shows the Kinetis UART continues to transmit after the receiver has de-asserted CTS: https://community.nxp.com/thread/432154 Freescale engineers claim their part is OK and its the other guys fault... Here's my question: As this is an asynchronous link, the receiver can de-assert CTS at any time. What is the tra

Hi, I'm using the MC9S12NE64 with the Freescale version of OpenTCP and I'm having some problems the the tcp/ip-stack. It sometimes doesn't ACK received data packets, which results in retransmissions. The problem doesen't seem to be related to high volume traffic all, tough the problem becomes more acute when a lot of data is being received and transmitted. Is someone using this tcp/ip-stack a...

I have a system based on the Freescale MPC5200B, running VxWorks, which has a strange problem. The system has a set of self tests which opens a socket server to the world. There is some PC software which opens a socket on the server for communication, and then the user on the PC can run batteries of tests on the card. The system also has a firmware uploader. It works in the opposite way ...

I want to upgrade from 8 bit to 32 bit microcontrollers. Which is the best platform to invest on? (I mean in terms of code portability/devices offer/tool reuse/long term device availability) ARM7 seems to be a good platform... Many company are proposing low cost ARM7 microcontrollers: *) they (obviously) share the same instruction set and core specific behaviours (i.e. cpu states...) *) ...
