Hi there,I have 2 modebus register 0x0010, 0x0011. These are enable encryptionkey value. There square vaule should be less then 255 for some reason. This modebus register can be allowed for certain command functions as follows.void ModebusSetCMD_ENE...
I'm sure ST must have a better idea than we do. Distributors seem to be saying "not in the foreseeable future", which I take to mean at least the end of 2023. Obviously no-one has a crystal ball, but a guess would be better than nothing. It does...
Could someone tell me, what I'm doing wrong? Why can't I find out the memory value in "Memory browser" window?Very simple code: uint8_t p = HAL_GPIO_ReadPin(LED_GPIO_Port, LED_Pin); printf("Address of variable 'p' is: %p\r\n", &p); // 0x20004ff7
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
Writing bytes to internal flash memory blocks all interrupts on the STM32L0 despite moving the vector table and ISR functions to RAM The ContextI have a embedded system running on an STM32L053 processor that needs to process STM32 hardware timer inte...
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...
