Posted on October 15, 2015 at 17:00 I've just wasted an STM32405 chip + a day of my time trying to work out why the USB FS CDC device wasn't working on a new (partially populated) board that I was testing. Why wasn't the USB working? Well, the board...
Posted on September 01, 2015 at 00:51There is a checkbox named USART1 global inrterrupt in Cube NVIC settings. Are there any local interrupts? I used settings for F100 cpu.
Posted on October 06, 2015 at 17:44If I build a Cube config using the stm32f303vctx processor and enable an I2C port, I get HAL_I2C_MODULE_ENABLED in the sources and a hal_i2c include file included. However, if I use the 'stm32f3discovery' board pro...
Posted on October 12, 2015 at 17:02Hi to all, Did anybody experience random corruption of bits (not byte) on a SDcard..?We are using an stm32f217 with RTX, FlashFS and tcp from Keil, v4.70. uSD card is connected through SDIO port.We are using 2Gb uS...
Posted on June 19, 2013 at 22:17I'm trying to run the ADC Example code that came along with this board, but I keep getting stuck in a loop where the calibration bit (ADC1.CR - bit 31 of the control register) isn't getting set back to zero, and I'm g...
Posted on October 15, 2015 at 15:17Hello. I use STM32F429 controller with 12MHz HSE oscillator. Is it posible to clock RTC from HSE while controller supplied from VBAT pin only?
Posted on October 15, 2015 at 08:41 Hello, I 'm using a STM32F030C8 and I generate a tick of 1.136ms with the RTC with subseconds alarm. I calibrate the LSI with the HSI (=8Mhz) but I don't know how LSI and HSI frequencies change when temperat...
Posted on October 15, 2015 at 13:27Hi , I have an SPI program running successfully between two stm32f4 discovery boards using SPI_NSS as SPI_NSS_Soft. Some discussions on Stm32f4 SPI say that SPI_NSS_Soft has to be used when only one slave. Does th...
Posted on September 23, 2015 at 12:49Hello, there seems to be a serious problem with project re-generation with CubeMX. After regenerating a project, the linked files (for example HAL and configuration files, like main.c) point to the wrong directio...
