TFT_RST is whatever pin you want to use. Adafruit_ILI9341(TFT_CS, TFT_DC, TFT_RST); should work
Thanks, that worked.
By the way... I STILL am torn between using PA5/6/7 OR PB3/4/5 for SPI as default on Black F407 boards. PB4 has the problem of not being broken out on the headers, PB3 conflicting with jtag-SWO, and PAx is the default SPI1 in CubeMX, not PBx.
Yes, the decision seems not to be easy.
Probably we a list of mandatory Arduino interfaces would be useful:
- SPI ==> mandatory
- I2S ==> mandatory
- JTAG ==> use SWDIO debug interface
Because I have now the compiler for the STM32F7 Discovery, I tried the whestone benchmark
Loops: 1000, Iterations: 1, Duration: 2135 ms.
C Converted Single Precision Whetstones: 46.84 MIPS
Loops: 1000, Iterations: 1, Duration: 7740 ms.
C Converted Single Precision Whetstones: 12.92 MIPS
Both are to slow, because the STM32F4 Discovery has:
Loops: 1000, Iterations: 1, Duration: 917 ms.
C Converted Single Precision Whetstones: 109.05 MIPS
