I am a total newb, I just started looking into this today. I have a a chromebook running chrome Version 96.0.4664.111 (Official Build) (64-bit), and a raspberry pi pico which I have loaded python bootloader on (drag & drop). I am trying to access the pico from my browser serially to load my source code since I cannot install thawny on my chromebook. I have pieced together this javascript function that uses web serial api to connect to the pico.
const filters = [
{ usbVendorId: 0x2E8A, usbProductId: 0x0003 },
{ usbVendorId: 0x2E8A, usbProductId: 0x0005 }
];
// Prompt user to select an Arduino Uno device.
const port = await navigator.serial.requestPort({ filters });
const { usbProductId, usbVendorId } = port.getInfo();
// Wait for the serial port to open.
await port.open({ baudRate: 9600 });
const textDecoder = new TextDecoderStream();
const readableStreamClosed = port.readable.pipeTo(textDecoder.writable);
const reader = textDecoder.readable.getReader();
// Listen to data coming from the serial device.
while (true) {
const { value, done } = await reader.read();
if (done) {
// Allow the serial port to be closed later.
reader.releaseLock();
break;
}
// value is a Uint8Array.
console.log(value);
}
// Listen to data coming from the serial device.
while (true) {
const { value, done } = await reader.read();
if (done) {
// Allow the serial port to be closed later.
reader.releaseLock();
break;
}
// value is a string.
console.log(value);
}
const textEncoder = new TextEncoderStream();
const writableStreamClosed = textEncoder.readable.pipeTo(port.writable);
const writer = textEncoder.writable.getWriter();
await writer.write("hi");
// Allow the serial port to be closed later.
writer.releaseLock();
I cannot find a way to make this program upload a file, I would really appreciate it if someone could help me out. Please excuse me if I'm being unclear or extremley stupid, I am completley new to this and I am really tired from new-years last night. Thanks!
