STM32 Flash Loader Demonstrator support for STM32L071
Posted on August 22, 2017 at 17:25Hi,I am trying to use the STM32 flash loader demonstrator to download a new software on my device.I am using the version V2.9.0RC4, which I have found on this site (Cf. https://community.st.com/0D50X00009XkYFUSA3 )....
STM32H743I_EVAL ExtMem_Application LedTogging, how to load code?
Hi,I'm trying to load the LedToggling applicaton into the STM32H743I-EVAL board compiled with the XIP_QSPI_InternalSRAM configuration and using the EWARM.It is written in the readme.txt file that for the EWARM I only have to use is Project->Debug. ...
Linker problem on SW4STM32 - Undefined reference to HAL_I2C_MASTER_TRANSMIT
Hello, I'm using stm32l152re nucleo board and I've to connect an accelerometer with I2c. All is ok, but when I build the project the linker says "Undefined reference to HAL_I2C_MASTER_TRANSMIT". That's a function of stm32l1xx_hal_i2c.h and I can't un...
STM32F103XB: TIM2 CH1 on PA15 conflicts with SPI1 NSS
Posted on January 09, 2018 at 18:32Hi,Using CubeMX, I configured SPI1 on a STM32F103T8Ux as full-duplex master mapped on PB3..PB5, with hardware NSS (on PA15) disabled (set to SPI_NSS_SOFT in spi.c).So, PA15 should be available for TIM2 CH1 PWM outp...
Problems: STM32H743ZI two SPIs to receive data with DMA
Hello,I use STM32H743ZI two SPIs with DMA to collect data. The data are OK when only one SPI with DMA is activated. However, when I use two SPIs with DMA to collect data simultaneously, the data collected are not correct. The DMA setup:Codes to colle...
STM32F746G-DISCO - demo displays :scrambled'' pictures
Posted on September 04, 2017 at 21:53Hi,I had a few STM32F746-DISCO boards. This time I bought second hand board and uploaded demo app.All pictures are 'scrambled'. I cannot figure out what is going on. Seems like a hardware defect.Please share your...
Non linearity in ADC Measurement using STM32F051R4T6TR IC
Hai,i have been into designing a solar inverter using STMF051R4 series IC for past few years. Presently we are working on ADC Measurement with DC voltage.The problem we are facing now is we not able to get a linearity in measurement of the dc voltage...
Removing delay for escaping blocking in my code
Hi all, i have a function that changes the PWM value over some time.. the issue is it get blocked by HAL_Delay.. what's the way to replace it with some non blocking method ?void heartBeat_loop(uint8_t initial_val, uint8_t end_val, uint8_t n) { int ...
PWM TIM1 frequency differs from calculation
Hello,i have a simple task which turned to be more tricky than i expected.The system uses a 8mhz HSE.My clocks are :HCLK/SYSCLK is 100MHZPCLK1 is 25MHZPCLK2 is 50 MHZ ( 100MHZ for TIM1)I need to generate a 50% duty 100khz PWM signal via PE9 pin ( cha...
