I have a custom board, which uses STM32H747IXH6 and MB1166 LCD screen from the related discovery board. I am trying to get TouchGFX up and running on this custom setup, but in my PCB design, I missed out the dedicated TE pin in the connector (I'm fol...

I have a custom board with a STM32H747 micro on board, interfacing with a LCD driven by OTM8009A over the MIPI DSI interface. I have taken the driver code from the DISCO eval board which I used to design and build my board. On calling OTM8009A_Init()...

I have designed a custom board using STM32H747 with external SDRAM (IS42S32800J) via FMC, copying a lot of the design from the STM32H747I-DISCO eval board. I am currently bringing up the board and testing each component before I implement a TouchGFX ...

I am looking for some overview on my custom STM32H747 PCB design - mainly that my schematic for the power supply and VCAP etc. are correct The board is to be powered by SMPS.All comments welcome!

I have a setup on a dual core STM32H755 device with each core measuring two ADC channels with shared pins at different sample rates. The M7 core measures ADC1 Ch15 and Ch5 at 1MHz@14bit, with a sampling time of 1.5cycles (20MHz ADC clock prescaled by...

Sorted! I got it working with the example and then copied the TouchGFXHAL code to my custom project. The colours are wrong, but we're off to a good start!

I don't have an implementation of getTFTCurrentLine() in TouchGFXHAL, no. I have tried going from an example - just the blankUI example in TouchGFX designer for the STM32H747I-DISCO. I have had to make the following modifications to get it up and run...

This is the stack from the point that the task locks upWithout access to the HAL source, I can't probe this any further

One difference from STM32H747DISCO is that I am using the IS42S32800J SRAM chip instead of the IS32S32160D on the DISCO board. I have half as much memory at 256Mb instead of 512, but the access parameters are all the same (except for one fewer addres...

I did have enableMCULoadCalculation(true) set, but I have now removed it, along with mcuInstr.init() and setMCUInstrumentation(&mcuInstr). Unfortunately, this doesn't change anything.
