ch32v307 VS pico-examples

VCC-GND Studio is about to launch similar boards based on CH32V307.

But if you're looking for RISC-V + integrated PHY, take a look at WCH's CH32V307 - just add magnetics, termination and an RJ45 jack and you've got 10BaseT.

Yes, English datasheets can be found - along with code examples, board schematics etc - at the openwch/ch32v307 Github repo.

More realistically, I DO think there's value for a terminal server that's just an ethernet connection (even one that's ancient) with some amount of programmability that's connected to 80 GPIO pins, some of which may be serial ports. I could imagine testing 1-2 Raspberry Pi-class with a bed of nails style test jig that confirms that all the GPIO, JTAG, and such are at least toggleable by sending synchronized signals to the BeagleBone/VisionFive/ESP32-C3/ whatever to confirm that all the I/O pins survived the fine wires from the wafer to the package plus all intervening PCB vias and soldering and so on. (Maybe you can't test board X with another board X because there's a different number of inputs and outputs.)

looks to be IMAFC from the PDF on their github (https://github.com/openwch/ch32v307/blob/main/Datasheet/CH32V20x_30xDS0.PDF)

I really love the SSD1306 for its educational value. If you've bought a sensor kit for Arduino or ESP32 or Pico or whatever, chances are decent that you already have an SSD1306 lying around. There's so much example code for it. And the datasheet was pretty easy to grok IMO. My first exposure to it was in the pico-examples repo: https://github.com/raspberrypi/pico-examples/tree/master/i2c...

There's a few Rust libraries for it, too. And it's supported in Wokwi! https://wokwi.com/projects/425067706980448257

Unfortunately the starter example [1] hasn't made it into the public tree (yet ?)

The Pico SDK has a plugin based stdio, they give you two implementations: UART and USB CDC, but you can add new ones by implementing a few callback functions. The UART plugin provided with the SDK can be disabled and replaced, the default implementation is very simplistic and will block.

The USB CDC version is much faster but may not always be appropriate for your project.

I implemented one that uses a buffer and an interrupt to feed the UART in the background, and then I disabled the plugin the Pico SDK provided. I'm not using an RTOS.

The SDK example [uart_advanced](https://github.com/raspberrypi/pico-examples/blob/master/uar...) [github.com/raspberrypi] shows how to set up UART interrupts using the Pico SDK

Navigate to the Pico Examples repository.

I'm experimenting with the "pico/wifi/tcp_server/". It works as expected with a WPA2 secured network, however I can't figure out how to access a WP3 secured network. According to the Pico W datasheet the device supports WPA3. However the function cyw43_arch_wifi_connect_async doesn't seem to have the option to select WPA3. The supported options are CYW43_AUTH_WPA_TKIP_PSK, CYW43_AUTH_WPA2_AES_PSK, or CYW43_AUTH_WPA2_MIXED_PSK.

I connected the MPU6050 and Pico as shown in the wiring guide for the example code here and have also tried using a level shifter with this wiring setup.

There's an iperf opkg pkg, or is it just netperf (which works with fluent)?

Okay I abandoned both of those libraries and tried the simpler WS2812 example in the Pico SDK and I did get it working....finally.

For C++, you could look at the pico-examples on Github https://github.com/raspberrypi/pico-examples

I don't know what you mean. There are dozens of tutorials on the frontpage of google. And just straight up a bt folder of projects for the pico w in the rpi github at https://github.com/raspberrypi/pico-examples/tree/master/pico_w/bt. have you tried that? If you haven't, then you need to work on learning how to use google because people aren't here to do work for you. If you have tried this and it didn't work then reread my previous post and ask better questions.
