Ask questions, find answers, and share insights on STM32 products and their technical features.
So I'm trying to gain greater understanding on the STM32 tools on a project that I've inherited. I'm noticing that there are weak variables that are of global scope to a given file that are defined in multiple files such as follows:main.c:int g;other...
From the datasheet from the slave device: "First the host must write a command to the slave device. Then it must follow that command with a repeated start condition to denote a read from that device's address. The slave then returns two bytes of data...
Hi, i've been building self balancing robot, so i needed quite lot of periphelias to be working together, they are: I2C, EXTI's, two Timers in encoder mode, Timer in PWM generation mode and GPIO outputs.I'm using STM32CubeIDE 1.9.0., and STM32L432KC ...
I want to insert the string my_data_SRAM in the base address of the FLASH. I wrote this code and tried 2 ways:1) *((uint8_t *)BASE_ADDRESS_FLASH+i) = my_data_RAM[i];2) HAL_FLASH_Program(TYPEPROGRAM_WORD, (uint32_t *)(BASE_ADDRESS_FLASH+i), my_data_RA...
Did anybody already develop a code for SPI to I2C bridge using STM32CO? If yes, where can I find it?Thank you
The JTAG pin TDI shares functionality with the UART4 CTS function , how do I use CTS and and still program the part with the JTAG connector?Any help appreciated.Richard
The L6474 uses SPI in MODE 3 where CPOL = 1 and CPHA = 1My logic analyzer is saying that having the SCK low when the CS is pulled low or enabled the idle state of the CLK (a.k.a. SCK) is not correct for MODE 3. After the first transaction the SCK st...
On a NUCLEO-F401RE, I am observing strange conversion values when I apply higher voltage than Vref to an ADC pin and carry out conversion on it. I would have expected the converted value to be 4095 (0fff) but in reality it is more like 3233 (0ca1) fo...
I have configured the TIM1 with PWM CH1 and CH1N, with 62.KHz frequency .I am getting the 180 degree phase shift for 50 % duty cycle .If i vary duty cycle to 30 % then CH1 =30% and CH1N will be 70 % and it is inverted .I need same duty cycle with 180...
I have an STM32F403ZH Nucleo board and it's connected to three separate CAN channels. I would like to be able to receive identical messages on any channel (same identifier, baud rate, etc) and have the microcontroller be able to determine which one i...
