Posted on September 30, 2012 at 11:51Hello, I am new in programming of STM32VL Discovery. I would like to write program in assembler for blinking LEDs using interrupts. But it is so difficult to find examples in ASM and I can�t find some example in ...
Posted on September 29, 2012 at 07:26As far as I understand using of the standard ST bootloader is not secure because in this case FW can not be protected and may be read by anyone. I mean anyone can read my FW and theoretically copy it to its own p...
Posted on September 28, 2012 at 00:13 Hi, first of all thanks for reading this! This is assembly code (gnu arm) for setting up the ST32F103 to make sound out the DAC. It works in 48mhz PLL mode, but not in What follows is the complete progra...
Posted on September 22, 2012 at 20:19I have found a few examples of how to update the firmware on a STMF4. The first one you needed to use a usb memory stick and the second one you had to reset the microcontroller and put the boot pins in the correc...
Posted on September 27, 2012 at 11:26Hi, I use the STM32F0 Discovery. I disconnect jump JP2 and connect ammeter. I build a simple program in IAR: int main() { DWORD i; UINT16 j; SystemInit(); SystemCoreClockUpdate(); init_hardware(); ...
Posted on June 03, 2011 at 23:59Hi, I want to build circuit with STM32F107RC. I projected PCB and chcek all wires with any avaluation kit board. When I turn power on all circuit take about 9 mA. I chcecked all power supply pins aroud microcontroller...
Posted on September 26, 2012 at 14:37Hello all, I am doing a project where the microcontroller (STM32) is sending the parameters to the server via DHCP using wifi module. So, now i want to make available an offline web page to the user where he will...
Posted on September 28, 2012 at 09:25Hi all,I need to be able to reprogram an STM32F103 device in the field through a USB connection on UART1. It is critical that the firmware update is performed without any direct user intervention on the board (ap...
Posted on April 20, 2012 at 09:21I have recently assembled 6 PCBs with STM32F407IGT6 micros on them. I seem to be having a problem reading from RAM. This was first noticed when one of the boards was hard faulting and returning a non-precise bus erro...
Posted on September 28, 2012 at 19:28Hello, I've been wondering about upgrading to the STM32 from an ST10. It's imperative that certain thing are as close to instantaneous as possible. I was thinking I've identified two bottlenecks and two soluti...
