Can I use the Quad SPI memory controller peripheral on STM32F4xx series to access a PSRAM or SRAM IC rather than a flash IC, and have the data memory map as if internal RAM?
I am hoping to use the CMSIS/DSP libraries to work on data that I periodically store on external RAM. If it is important, my current plan is to use the Lyontek LY68L6400 PSRAM or the VTI7064 SRAM (more expensive). Both are 64Mb volatile memory ICs th...
Resolved! FMPI2C (STM32F446) working as I2C slave is not releasing the SDA line after ACK
Hi The STM is configured as NOSTRETCH=1 and connected to a RL78 which acts as master. The whole configuration is used to test the SW on the RL78. The STM is emulating a number of I2C devices. The RL78 can not handle clockstreching on the used ports.S...
Implementing controlled phase shifted PWM on STM32F051R8T6 or STM32G030C8
I want to develop a full bridge converter, for which I need two PWM channels with complementary outputs. In order to turn off the load, I need to implement phase shift on one of the PWM channel and its pair(as shown in the image). I began by using ST...
PDR_ON effects to VBat?
Datasheet says Yes, but as we tested, RTC still runs (hold data after disconnected power), no matter what state of the pin is.Thanks for any suggesstion!
Resolved! How to phase shift two complementary PWM signal based on some internal TIMER event?
I am using STM32F051R8T6. My application is to drive a full bridge configuration, for which I require two pair of complementary PWM signals with dead time insertion. So far I have been able to achieve this using two channles of a timer( CH1-CH1N and ...
Interfacing between SMT32F and ST L6206
Previously I've designed a motordriver based on an STM32F303 and an ST L6206 Dual Full Bridge driver. I've had some issues with the interfacing between the MCU and the bridge driver, because the MCU works on 3V3 and the bridge driver works on 5V. So ...
UART not working on STM32F4 when GCC compiler is in O0 (None) optimization
In the last week I had to debug my MODBUS RTU slave application on my custom board for a communication issue on my RS485 network.My board is based on the STM32F411VET6 mcu and I developed my application with STM32CubeMX v5.0.0 and STM32F4 Firmware Pa...
Problem with WiFi Connection in board B-L475E-IoT01A2
I have purchased a B-L475E-IoT01A2 board that WiFi connection works well in the company. But the problem is that when I take this board home and test it, it doesn't connect to Wifi. It should be noted that in both cases, I test this board with my mob...
flash using USART for STM32F303E- eval
hi stm,i want to flash using USART. what is procedure.flashloader demonstrator is not working, it is getting hanged (win 7). but target is WIN XP.mcu board is need to connect with WIN-XP PC. how to achieve the target.
