Hi All, I am facing an issue with the USART Transmit. My code is as shown below...... #include #include void main( void ) { char group[10]="Microchip "; int i; OpenUSART( USART_TX_INT_OFF & USART_RX_INT_OFF & USART_ASYNCH_MODE & USART_EIGHT_BIT & USART_CONT_RX & USART_BRGH_HIGH, 129 ); while( 1 ) { for(i=0; i

Gentlemen: I've put together 68k embedded systems using my employer's ICE equipment, but what is the minimum amount of electronics necessary to setup the p18f4431 utilizing Microchip's ICD2 equipment? Once operating I'll explore PWM, LCDs, A/D interfacing and all that on my own, but I'm needing a push or hint at this moment. Current setup isn't quite enough. Thanks in advance. 2Pe...

Greetings. I have a small embedded application to develop that needs 1) a UART, 2) SPI (or other interface for flash-based card memory, SD preferred), 3) A/D, 4) D/A (PWM OK), and 5) a USB 2.0 port. The Microchip PICs 18F2550 or 4550 would appear to be a great fit (performance, memory and cost too) except ... They put the UART receive data input (RX) and the SPI data output (SDO) on t...

While we are talking about Microchip, has anyone tried using the PIC32 as a USB bus powered device in your own circuits and did you have any issues as result ? It's on my todo list in the upcoming future, so I am trying to find any possible issues upfront. I've done some searching online but I keep hitting stuff for the PIC18 or even the PIC24 instead. I have not found anything explicit ...

Unbelievable..... I'm playing around with the Microchip C18 compiler after a hair-splitting experience with CCS. Apparently the optimizer of C18 is not that good. For instance: LATF = addr > > 16; where addr is an uint32, is compiled into a loop where 4 registers really get shifted 16 times in a loop. Any decent compiler should recognise that a shift by 16, stored to an 8 bit port could ea

Hi all, This is again a follow up on EEPROM discussion I had previously a few days back.Regarding I2C based EEPROM I recently came across an application note from Microchip company (Document name AN709). The note says : "FORCING INTERNAL RESET VIA SOFTWARE In all designs it is recommended that a software reset sequence be sent to the EEPROM as part of the microcontrollers power up seque...

I recently purchased a clone Microchip PIC debugger from some Chinese importer http://www.virtualvillage.co.uk/Items/006401-001? (bad idea probably, I know). I set it all up, it programs perfectly and does a POST fine. The problem is with debugging. I hit the 'program' button on MPLAB, the PIC is programmed fine but I get an 'ICD0083' error (cannot enter the debug mode on the chip). I'v...

Hi! I hope somebody can help me with this problem or at least give me som suggestion how to solve it. I have a DSPIC CPU conected to at CF to store Data of course. To save power the CF power is turned off where ever it is possible. Power on sequense is as follows.

Does anyone know if any of the Microchip PICmicros reset their divide-by-four instruction counter during a hardware reset? I need to drive an array of PICs from a single clock, and more than that, I need all the PICs to be exactly synchronized with respect to their instruction cycles. I am hoping that releasing them from reset at the same time will accomplish this goal. I am looking primar...

I have been trying to use the PICKIT 2 programmer option within MPLAB IDE, but it seems like the option to do so is disable as shown in http://imagebin.ca/view/86lX0hhQ.html. I have also tried to update the firmware of my PICKIT 2 separately on the software provided on the Microchip website, but it keeps on freezing regularly every time I have attempted to check my PIC18F2620 to see if it is ...

Hi, I'm just getting started in AVRs. The only other microcontroller I use frequently are the Microchip PIC devices, and I have some (very basic) questions. 1) If something in data memory space isn't a register or RAM, is it a port? 2) Ports are mapped in the data memory space, and not a seperate I/O space - so why have does the concept of ports exist at all? Is this for ...

Hi So, considering going the Cortex Mx route for project with new microcontrollers at our firm. Has anyone a feeling/information about the development speed of the ARM Cortex Mx series vs the rest of the industry? Meaning, that potentially the same core strategy for the ARM, licensing to toher manufactors mean that they may have faster development speed that others (Microchip, Renesas, wh...

The sample thermo.zip at http://173.224.223.62/pic32 print out the pointer of a global variable. Linker place it in page A0. Microchip ran it on their simulator and they got the correct result. I ran it on the real chip and got pointer at page 7F Why, oh, why? Anyone care to give an explanation? I can lend out a test board if necessary, but right now we are short on hardware....

I worked with NXP Cortex-M3 LPC1768 and similar and Microchip/Atmel SAM D20/C21. I didn't like Atmel Software Framework so I extracted a buch of low-level files from ASF (mainly headers to manipulate registers) and rewrite the high-level drivers for peripherals I used (UART, ADC, Timers, ...) It wasn't a simple task, I spent many days to understand what ASF really do, decide what to ...

I'm looking for a microcontroller with low speed USB 1.1 support in a DIP package, and with onboard Flash (ie: not a OTP chip). I know about the HC08 JB8. I also see that Microchip do a PIC one as well. Are there any others ? (I'm in the UK in case that makes any difference in availability) Thanks for any information.
