SDRAM Module Tester based on STM32F429

Hello everyone,I need to build a system to test a bunch of existing memory modules built around 512 Mbit SDRAM chips (4 chips each for total of 256 MBytes). The attached schematic shows the original design of the memory module and how it's connected ...

I am looking for an easily available MCU to do a simple analog readout through a 32position mux and CAN-Bus connection. With my very limited understanding I looked at the stm32f0 series. But some of them are hard to find. Is there a better option? Thanks

Multi-channel on STM32F429DISCO not working

Hello,I use a STM32F429DISCO REVE01 with a MCU STM32F429ZI.I have to use the ADC. On PA0, I connect a sensor with an amplifier and it's work, but when I want tu use ither channel like channel 1 with PA1 pin, that's not work, my value is around 0.Why ...

How to implement the program for PWM generation in stm32f051c8t6tr

I working on stm32 microcontroller, I want to generate the pwm signal for stm32f051c8t6tr mcu. I have assigned my prescalar as 48-1 and counter period is 1000-1 in order to generate 10KHz frequency.My code is TIM1->CCR1=50;HAL_TIM_PWM_Start(&htim1,TI...

Debugging the MCU on a NUCLEO-H7A3ZI if 1.8V is selected?

Dear all,It seems like I actually broke two Nucleo 144 with a H7A3 and H723 after I tried to debug the MCU with the on board debugger and after switching the supply voltage for the MCU to 1.8V (no connection from debugger to MCU possible, even not wi...

APS6408L-3OBM-BA RAM not working with stm32h723 processor

hello everyone. I have a question. I am using APS6408L-3OBM-BA as external RAM in a project. First, I used the APS6408L-3OBM-BA RAM on the STM32L4P5G-DK board as memory mapped, but when I use the STM32H723VET6 processor, I cannot run the RAM. HAL_RCC...

STM32L433 clock is running in stop 2

My issue is a high current in stop 2 mode with the STM32L433, i'm measuring around 1mA in Stop2 Mode, which should be around 5uA for the MCU, with the rest of the board compoents, i expect around 50uA. For investiagrion, i desoldered all other compo...

How to read status of PWM pin accurately ?

I am using STM32F407VG development board to implement Direct torque control with space vector modulation of induction motor drive. I want to read status of PWM pins accurately in order to estimate phase voltage from DC link voltage and status of the ...
