I'm try to simulate a very simple program:
#include <stdio.h> #include "pico/stdlib.h" int led_state = 0; int main() { const uint LED_PIN = PICO_DEFAULT_LED_PIN; gpio_init(LED_PIN); gpio_set_dir(LED_PIN, GPIO_OUT); stdio_init_all(); while (1) { printf("Enter 1 to turn the LED on, 0 to turn it off\n"); led_state = getchar(); led_state -= '0'; gpio_put(LED_PIN, led_state); sleep_ms(100); } }
I was able to figure out how to show the serial output.
const hex = fs.readFileSync('Test2.hex', 'utf-8'); const mcu = new RP2040(); mcu.loadBootrom(bootromB1); loadHex(hex, mcu.flash, 0x10000000); mcu.uart[0].onByte = (value) => { process.stdout.write(new Uint8Array([value])); }; mcu.gpio[25].addListener ( (value, lastValue) => { process.stdout.write("--- PIN 25 ---") process.stdout.write("Changed from "+lastValue+" to "+value) } ) mcu.core.PC = 0x10000000; mcu.execute();
How do I read from the serial?
You mean how to send data to the serial port?
mcu.uart[0].feedByte(value);
