Posted on July 05, 2017 at 20:45With the STM32L476ZGT6 Evaluation board, which I've just started to use, I tried the LPTIM_PWM_LSE demo successfully (after modifying timer frequency to make LED blink at 1Hz). I then attempted to change the demo to u...
Posted on March 20, 2017 at 08:40I tried to update STM32CubeMX yesterday to V4.20 using the built in updater (via Check Update Manager). After files were downloaded the update process started normally. Right after installation appeared to have compl...
Posted on July 06, 2017 at 08:00Hello everybody,I am using I2C interface in master mode to collect data from external slave device with DMA in non-blocking mode.- HAL_I2C_Master_Transmit_DMA- HAL_I2C_Master_Receive_DMAMy program is working fine sinc...
Posted on July 05, 2017 at 13:52Hi,There is a bug in F0 LL library rcc module.RCC_GetSystemClockFreq() is incorrect if the mcu use HSI48 as system clock,in this case it returns HSI_VALUE but not 48MHz.
Posted on July 04, 2017 at 21:00Dear all, We have been developing a custom board featuring STM32F746ZGT6, and we have encountered some problems. We are able to program the MCU using the ST-link with no problems, however, the MCU does not do anyt...
Posted on July 06, 2017 at 18:15Dear Support,Hi,I've created two PWM with a 50% duty cycle using STM32F103 and its timer8. Now I would be grateful if you tell me how to shift one of the PWMs?#stm32f103-shift-pwm
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...
