Posted on July 06, 2017 at 11:08The problem is simple ...I am using the UART with DMA to copy 10 bytes to a memory location.Sometimes (due to some error) 11-byte packets are sent to the MCU. What happens is that the DMA will transfer the 10 bytes an...
Posted on March 24, 2017 at 12:52I see when you change settings on RCC, from internal oscillator to external, both line on .ioc file are setted and the code generated is this:RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSI|RCC_OSCILLATORT...
Posted on July 07, 2017 at 08:45We are using an STM32F429 together with external SRAM, SD card and LCD display, utilizing STemWin. The framebuffer for the display is located in the external SRAM, as is another buffer that is used to write to the SD ...
Posted on July 04, 2017 at 07:57Hello, everybody.Hello everybody. I use Keil and ST-Link for programming STM322L073 Flash and EEPROM. I try to program them simultaneously but only Flash is written.Is there any way of writing Flash and Internal EEPRO...
Posted on July 06, 2017 at 05:53I am working with the STM32F429 and we use the timer pwm output as the ads1271 CLK。 we get the wave as the picture showWe think CLK quality is poor,so the sample rate is inaccurate. Any ideas ?Thanks,End.
Posted on July 07, 2017 at 04:46Hi There,I am using STM32F429ZI discovery board to write an UART and LTDC code.I have Entesla serial to USB converter connected to the Discovery board via TTL(I am not using RS232).Simple use case is -Display the char...
Posted on July 06, 2017 at 21:02Hi,My stm32 board has four uart ports. Each of them is connected to rs 485 transmitter (tx only).I'm looking for any ideas how to extend my project to have more than four uart ports - up to 10.My first idea was to con...
Posted on June 23, 2017 at 09:26Its very strange to me .. I tried to recognize the problem by checking all datasheets information and search for same situation in the net, but unfortunately I find nothing .. please help me.the base issue is when i r...
Posted on July 06, 2017 at 15:00Designing own board based on stm32L0x1 and looking at debug provision.Am I right in thinking that printf style output is not available via the debugger ( ST-LINK/V2) on the stm32L0 (m0+) parts as:-1) They only have SW...
Posted on July 06, 2017 at 13:26Hi there,As mentioned above, I need to operate STM32F2 at 2.5V and the peripherals which i am gone use are USART, I2C, FSMC, ETHERNET, USB_FS. I have seen the datasheet for limitations depending on operating power sup...
