Looking to make a microtonal music keyboard. I would like to find a STM32 lay out for a standard, midi, with velocity sensing keys (timing between two contacts per key) keyboard and with the C program that I can use as a guide to modify for my use.
Any Algorithm for scanning, timing velocity, and or to midi would help. I could do the matric lay out. I do not want to reinvent the Wheel if posable.Thank you, ƒg.
Resolved! Error in RM0432 Rev 9 for MCOSEL[3:0]: Microcontroller clock output ? EDIT: Sorry, no error in the manual.

About starting and stopping a timer by an encoder timer
Incremental encoders are known to have problems for speed measurement at low speeds. For this, period measurement at low speeds is recommended.The following statement is taken from RM0440 page 1158. What I want to do here is to start another timer in...
Resolved! STM32F4 DMA FIFO + SPI_TX = FIFO error, but work
Good afternoon! I am trying to establish the transmission of data via SPI to the display with DMA. The transmission is working, the display is completely painted over, but the FIFO error flag is set in the DMA registers.MCU: STM32F401CEU6 alignas(32)...
bxCan Filtering
I've been reading several forums posts about filtering, and other resources such as:https://community.st.com/s/question/0D50X00009XkfSlSAJ/can-filtershttps://blog.csdn.net/flydream0/article/details/52317532I get the gist of this.CAN_FilterIdHigh is t...
We are using STM32F103xB. We intend to replace STM32F103xB this with STM32F103xC, STM32F103xD & STM32F103xE. We found difference in memory map section in the "Aliased to Flash section", when comparing both MCUs. Will there be a need for Software change?.

MDMA_STM32H7xx
HI. there are two TIM1 registers and you need to move its address 0x40010034 from one register to another register 0x40010038 exactly 64bit, that is, a double word. is it possible to do this with MDMA single? the documentation is very poor. I had to...
Reading a very slow PWM frequency
Hi,I need to read a PWM that a rotating wheel generates (16 pulses per revolution) and I want to use one of the STM32F429 timers to do it. The problem is that the period goes from 7.8ms to infinite (no pulses), so I don't know what will happen if the...
