I use OCTOSPI as SPI master and listen via SPI3 as Slave (in SW NCS mode) what was sent from master.SPI3 Slave fails for clock speed 80 MHz (larger as 54 MHz:(Symptoms:the data bytes on SPI3 slave are wrong (they look like shifted by one bit)running ...
Hi.I made a custom board using stm32f767connect Coincell (CR1220) to VBAT and turn it off, I think I'm going into some modeSometimes it does not go into the main when the power is turned on again, and the battery life is short when the power is turne...
Hi everyone can you Please help me to solve this problem,In stm32mp1, Modbus RTU HW handshake communication is not established after Timeout,So after timeout try to reconnect againCTS line is always highCTSIF SR is getting set,Busy flag is set,And RT...
Hi all,I was trying to write to the codec (WM8994) I2C3 in the STM32F746 Disco board without luck. After trying a few things and looking at the data on my scope I realized the codec was not acknowledging the address. The problem is I was using 0x68 (...
STM says: OCTOSPI can generate a "regular SPI" transaction. But is not true:A "regular SPI transaction" means actually on OCTOSPI: a half-duplex SPI transaction (using just IO0, but for both directions).I you want to generate a "regular" SPI transact...
Hi, when configure MCU to deep sleep mode as the low power mode, it seems okay when debugging. But, when only power up STM32C0 by just connected its vcc and ground, it do not enter its interrupt. How can I solve it?My project goals are to achieve low...
"I used the STM32F746ZG to read the current from an ACS712 sensor, but the problem is that the ADC is not stable. I tried using an STM32F466RE to measure the same current, and this time the ADC is stable. I don't understand why, despite the ADC chara...
I've tried to see if I can get away with using just one bank address pin for a 4-bank SDRAM (IS42/45S16160J). My understanding is that this would half the addressable memory, as I could only access two banks instead of four.In the STM32H7 user manual...
Hello everyone,I intend to migrate an LPC development to the new stm32h5 family, I find the versatility that its flash offers very interesting. Being able to separate a set of memory into two blocks to run the main program without the need for an IAP...
Using the STM32H747I-DISCO, I am having problems getting SPI working at all.I am using SPI5, to allow connecting an X-NUCLEO-NFC08A1 directly via the Arduino headers.I do not see any data on the SCK line and HAL_SPI_Transmit() always fails.Looking in...
