How to display 14-bit gray pixel data through LTDC module.

2022-04-25
I'm testing the 14-bit (or 16-bit) output from ADC to display using LTDC module.There is L8 mode among LTDC input types, so I checked the ADC output by normalizing it to 8-bit.But, what i really need is 14-bit (or 16-bit) gray output.I want to know h...

STM32H7B3I-DK ADC Control register(ADC_CR) BOOST bits

2022-01-18
I'm checking the ADC operation with STM32H7B3I-DK board.​To set adc clock frequency up to 50MHz​, i tried to change BOOST bits of ADC_CR register.​However, unlike the rm0455 document that states that bits 8 and 9 (BOOST bits region) can be set, when ...

Is it possible to trigger serially using timers.

2021-03-07
For example, there are 3 timers (Timer 1, 2, 3).I want to set like below: Timer 1 : MasterTimer 2 : Slave of Timer1Timer 3 : Slave of Timer2When I checked the waveform after setting similarly to the above, it seemed that timer2 could not trigger time...

Can LTDC (LCD-TFT display controller) module be used for general digital video output?

2021-01-25
Currently, i am developing a camera module using STM32F769NI.​When i was trying to figure out how to output the processed video data, i found LTDC module.​​I am wondering if this module can ​be used for digital output in general, ​even if the LCD pa...

Infinite data transmit using SPI

2021-01-06
I am testing with STM32F769 Discovery board to make video syncs (not vsync, hsync).I am using SPI module to make infinite clock and data.But, it seems not supported in normal and DMA transmit mode (there is delay between transmissions).How should i ...
