Posted on January 21, 2013 at 07:45Hi is there any way to configure usb_vcp on stm32f103 like usart interrupt mode - just recieve only one byte . I use function compose_packet(received_byte) in all my USART_IRQHandlers and i want to use same functio...
Posted on November 20, 2012 at 14:04My application requires a BOOT loader that loads an application into a FLASH device. I have created two different applications: A BOOT loader application. start 0x08000000 A FLASH application. start 0...
Posted on July 12, 2012 at 07:09hi, i search and search but i cant find where i can change Vector Table base location in memory.map i can find .text 0x08004000 0x718 *(.isr_vector .isr_vector.*) .isr_vector 0x08004000 0x124 ..\obj\startup_stm32f...
Posted on July 03, 2012 at 08:32hi i want to place value - ''address of station'' at fixed memory address without specifed address its look like &sharpdefine mcu_address 0x03 i found - it may looks like &sharpdefine mcu_address (*((volati...
Posted on June 18, 2012 at 07:40HI I want to use DMA to Recieving data via uart (rs485) I want to use 20byte buffer but for siplicity in this exaple is shown only 1byte buffer... int main(void){ RCC_Configuration(); GPIO_Configuration(); USART...

So i got it .....
u8 RX_test [4];
u8 RX_lenght=0;
void USB_LP_CAN1_RX0_IRQHandler(void)
{
USB_Istr();
if ((count_out != 0) && (bDeviceState == CONFIGURED))
{
RX_test[RX_lenght++]=buffer_out[0...
Posted on July 13, 2012 at 07:10ok i read more and .... i think i was wrong - i must set VECT_TAB_OFFSET in bootloader not in aplication so for example bootloader location is 0x08000000 length 4000 aplication location is 0x08000000 length 4000 and i...
Posted on July 13, 2012 at 06:57ok but then my application will be on address 0x08000004 :) but i want have application on address 0x08004004 and told it to use vector table on address 0x08000000 my bootloader starts at address 0x08000004 i want t...
Posted on July 10, 2012 at 14:27Hi , I am going to write custom bootloader to all i need is simplest example for stm32 about that you was talking....have you any idea where can i find them ?
Posted on July 04, 2012 at 07:38ok - so i used this in my code and it works great : #define rts_1 GPIOA->ODR |= (1 << 12); //rs485 #define rts_0 GPIOA->ODR &= ~(1 << 12); //rs485 #define adresa 0x03 ...
