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...
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...
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...
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...
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 ...
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...
I have an application which I’m trying to make absolutely “bulletproof�?, so I’m trying to imagine and handle absolutely every possible failure scenario (specifically this query relates to hardware failure scenarios rather than software bugs).I was w...
How to use "TIM2_CH1" Timer interrupt to make toggle LED at PA0 every 1sec -I verify PA0 LED is good work(test with "HAL_GPIO_Toogglepin()") -contains cubeMX project files, Truestudio projets-my addtional user code down below-cubeMX select option is...
Hi Team, I am working on STM32F100VC for a flow sensor project. Here i am planning to use a Timer as Counter to read the pulses of flow meter. If i give 50 count, after sensing(counting) 50 pulses, i should get an interrupt. Then i can do the require...
I can connect with JTAG via SWD and load a simple program but after load the system won't run to main. The chip seems to be stuck in some hardware system reset loop. Attached is an image of the nRST pin. I've gone through AN4661 many times and ca...
