SPI to I2C bridge
Did anybody already develop a code for SPI to I2C bridge using STM32CO? If yes, where can I find it?Thank you

STM32L471RGT6 sharing UART4 CTS and JTAG
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
When SPI in Mode 3 is there a way to set the SCK or clock signal high before the first SPI transaction?
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...
STM32F401RE ADC conversion when Vin > Vref+
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...
STM32G431RB Two PWMs with 180 degree phase shift
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...
Resolved! How to differentiate which CANBUS a message is received on using STM32F4?
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...
STM32G4, CDC and RS232 signals
Hello all,I have a RS232 device (diagnose interface) that I want to replace with a Nucleo-G431KB board. To make it work I would like to use CDC (virtual port), but I need the RS232 specific signals, especially DTR/DSR, CTS/RTS... I looked in the exam...
Boot from Bank 2: nSWAP_BANK vs. BFB2
I am trying to implement a "dual bank field upgrade" with a STM32G0B1CEU6 as described in AN4767, chapter 2.4 (for a STM32L0). As far as I know the STM32G4 also has this functionality, not 100% identically implemented but with the same intention. See...
Doubt regarding multiple button press on STM32.
Hello,I had a doubt regarding multiple button presses. Im trying to code a program so that every time I press a button the brightness of the LED decreases and once it reaches the minimum (5th button press), it increases back again after every button ...
External input voltage supply for Nucleo-64 board
As per the user manual, we can power up a Nucleo-64 board by applying an external +5V to E5V and setting the jumpers accordingly. I have connected a TFT display with the uC board through SPI and the display is working fine. But what I am surprised ab...
