I have a test board that works but the board layout for manufacturing does not boot load. I used ST-LINK to program the application memory and it appeared to run but when I reset the chip it no longer ran. Is there a way to examine bootloader memory...
Hi ;I need to know if it is possible to get 15 ADC samples from 15 ADC conversion ICs over SPI protocol with a single conversion trigger. My MCU has only 6 SPI peripherals and 3 of them have 16bits data size and the other 3 SPI have 32bits spi data s...
Hi Experts, PFA the hardware design. I am trying to send data to parallel (not cascade) 74hc595 over common bus lines from CD4094B. I am sending 16 bits to place first 8 bits in 74hc595(1) and second bits in 74hc595(2). But I am getti...
If a digital output pin value is changed multiple times within the same main loop, within the same interrupt, or within the same task and not separated by a delay then the output pin does not work as expected.This applies to both HAL_GPIO_TogglePin()...
Hello,i'm reading GPIO using internal instruction of GPIO_ReadPin function like "(GPIOC->IDR & GPIO_PIN_1)?1:0;" but i didn't get actual speed. So is there any alternative way to read GPIO fast ?Regards,Yash
The ContextI have a embedded system running on an STM32L053 processor that needs to process STM32 hardware timer interrupts regularly and cannot be disabled. These top-priority interrupts cannot be prevented because it could cause a failure in the wh...
I am using about 13 (PCA9554A & PCA9554AD) I/O expander IC to connect sensors to STM32 F103 micro-controller through I2C. Upto 3 PCA9554 IC works fine, but the moment I connect 4th IC, it starts to dump 255 from all the i/O Expander ICs.The data is l...
Hello. I am making software with STM32F030CCT6 processor. I am trying to make ADC with or without DMA. I always face this problem in F0 series. I can read only one channel. When it switches to multi-channel, it transfers data from a single channel to...
HAL_Delay() function gives infinite delay.i am toggle led using delay.below my simple project files.
Marking on actual part STM32L151R8H6A is “151R8H6A�? but data sheet is “L151R8H6A�?
