That’s what i used for most… The SPI always finishes with OK response, confirming 25600 bytes have been transferred. First sections (line0 to line15) is for external interrupt from GPIO pins (P0 to P15). 1. However, it is also not possible to use lwip with the WF111 to my knowledge, since the SDIO interface on that module still requires special communications using the Synergy/Unifi drivers provided by CSR (intended for a Linux platform). You can use any one them in your application, this example uses I2C1 to communicate with 24C512 EEPROM, you can similar kind of code and methods for I2C2 & I2C3. These external interrupt lines is consist of 2 sections. It seems that I cannot trigger on clock and capture anything. Configuring GPIO on the STM32F4xx Introduction Configuring general purpose input/output (GPIO) on the Cortex-M4 takes more effort than you might think. Sep 15, 2013 · Using the DMA controller on STM32F4. You might try unmodified example code or at least using someone else's proven library rather than immediately trying to DIY, look at the SPI lines with a scope or cheapy logic analyzer or see how things look from the Arduino's perspective.
