Re: Nucleo H743ZI + NHD FT813 3.5"

These are the modified variants with SPI3 active and some extra working frequency In some days we will have the Github repository online, with the modified library GD23ZU. We will gladly share the link in case someone wants to experiment with these FT81x TFT's In order to gain access to the SdFat l...

Nucleo H743ZI + NHD FT813 3.5"

After a couple of years with the H743ZI core board in a drawer collecting dust, we finally managed to use it to connect a 3.5 "FT813 screen in SPI1 and in SPI3 a microSD reader for multimedia handling. The Greiman SdFat library can work in core 1.8.0, so we have used it to manage multimedia files (j...

Re: Release 1.8.0 is available

Thank you!. 1.8.0 installed. Since the version 1.6.0, the pin mapping of the nucleo-F767 variant does not address the SPI1 and SPI3 pins correctly. I enclose the mapping that I used to access both buses. With this mapping it is possible to simultaneously activate FT81X chip screens (in SPI1) and a m...

Re: STM32F407VE SDfat error compiling

Certainly, I experimented with the arrangement I had on the table hehehe. As mentioned by xtream123 previously: SPIClass SPI_3(3); SdFat sd(&SPI_3); The most recent SdFat version threw me an error in DMA, I had to modify a line in the SdSpiSTM32.cpp file from the SdFat library: From: #elif defined (...

Re: STM32F407VE SDfat error compiling

This example is the one that worked in an F767ZI core, with the official STM32 core and the latest version of the Greimann SdFat library /* * This program attempts to initialize an SD card and analyze its structure. */ #include <SPI.h> #include "SdFat.h" #include "sdios.h" // Set USE_SDIO to zero fo...

Re: STM32F407VE SDfat error compiling

Inside of the SdFat Config.h file, modify the value of this line:

Code: Select all

#define USE_STANDARD_SPI_LIBRARY 0
for this:

Code: Select all

#define USE_STANDARD_SPI_LIBRARY 2
Maybe it helps.
