ESP32 C3 Support
apcameron opened this issue · 5 comments
I have managed to get this running on my ESP32 C3 which has a RISC-V Processor.
I added a SD Card and wired it according to the pins listed below
Below is my hardware config file called esp32-c3.h
``#ifndef ESP32_H
#define ESP32_H
// SPI_DRIVER_SELECT must be set to 0 in SdFat/SdFatConfig.h (default is 0)
SdFat SD;
#define SCK 0
#define MOSI 2
#define MISO 1
#define SD_CS 10
#define SPIINIT SCK,MISO,MOSI,SD_CS // sck, miso, mosi, cs
#define SDMHZ 20
#define SDINIT SD_CS,SD_SCK_MHZ(SDMHZ)
#define LED 5
#define LEDinv 0
#define BOARD "ESP32 C3"
#define board_esp32
#define board_digital_io
uint8 esp32bdos(uint16 dmaaddr) {
return(0x00);
}
#endif
Awesome news. Have you joined our Discord already? The invite link is on the readme.
@apcameron
I also did get RunCPM to work on a ESP C3 last May ;)
Does also work on a ESP S2.
The next test will be the Lilygo T-Dongle S3 with ESP-S3 MCU ;)
This is my

No I prefer not to use discord.
I understand. It is just that there we have a team of users always online, so often things are answered quicker.
But hey, happy that you are enjoying RunCPM.
