sh1107 Driver for esp-idf

I used this font file.

Software requirements

ESP-IDF V4.4/V5.x.

Note for ESP32C2.
ESP-IDF V5.0 ESP32C2 i2c driver has a bug.
ESP-IDF V5.1 is required when using i2c of ESP32C2.

Note for ESP32C6.
ESP-IDF V5.1 is required when using ESP32C6.

Installation

git clone https://github.com/nopnop2002/esp-idf-sh1107
cd esp-idf-sh1107/TextDemo/
idf.py set-target {esp32/esp32s2/esp32s3/esp32c2/esp32c3/esp32c6}
idf.py menuconfig
idf.py flash

Configuration

You have to set this config value with menuconfig.

• CONFIG_INTERFACE
• CONFIG_SDA_GPIO
• CONFIG_SCL_GPIO
• CONFIG_RESET_GPIO
• CONFIG_MOSI_GPIO
• CONFIG_SCLK_GPIO
• CONFIG_CS_GPIO
• CONFIG_DC_GPIO

sh1107		ESP32	ESP32-S2/S3	ESP32-C2/C3/C6
CS	--	GPIO14	GPIO34	GPIO3
DC	--	GPIO27	GPIO37	GPIO2
RESET	--	GPIO33	GPIO33	GPI10
MOSI	--	GPIO23	GPIO35	GPIO0
SCLK	--	GPIO18	GPIO36	GPIO1
GND	--	GND	GND	GND
VCC	--	3.3V	3.3V	3.3V

You can change it to any pin using menuconfig.

Note
For some reason, there are development boards that cannot use GPIO06, GPIO08, GPIO09, GPIO19 for SPI clock pins.
According to the ESP32C3 specifications, these pins can also be used as SPI clocks.
I used a raw ESP-C3-13 to verify that these pins could be used as SPI clocks.
