Hi all, I’m new to using the Wio Lite series and purchased the Wio Lite RISC V for a simple thermostat project of a couple sensors an Hbridge.
I decided to use the Wio Lite RISC V as an affordable option that will be low power as my application will always be active. I’m having a couple problems that I can’t find any solutions to online, and figured I could use some official support as this product is quite new to the market as I can tell.
I’ve got the board working in a simple Blink LED capacity using the the sample Arduino framework and uploading using the DFU tool. Important to be noted, to get this working I had to use the board ID: gd32vf103v-eval instead of the recommended: wio_lite_risc-v due to missing library files. As of now I still have troubles locating certain drivers:
Anyways, onto the main support I’m looking for. I’ll format my main problems by number though going forwards:
1) The sample code at https://wiki.seeedstudio.com/Wio_Lite_RISC_V_GD32VF103_with_ESP8266/#resourse does not compile due to errors with the Serial references that are noted as not declared.
I’m not sure if they are expected to come from the Arduino libraries, or other ones, but I’m not quite sure how to proceed. If these are from some files I’m missing, or where to move forward. There are no working projects based off this that I can find online which is a little discouraging while hacking away with a new MCU.
2) Maybe 1b)?, but is it necessary to have a USB to TTL to program this device for WIFI used through the ESP8266 module?
This one I’ll admit is on me, I didn’t read through all the documentation while purchasing this product and was hoping that there would be some sort of API to use the wifi module. It’s okay if there isn’t as I can spend some time picking apart the sample code, but is the USB to TTL connector needed? I don’t quite understand why the GD32 can’t run code that would ideally connect to an existing network with constant SSID and password. I apologize if I’m being a bit naive on this issue, but I’m genuinely looking for some help here.
These feel like they are pretty basic startup questions, but the online support on this board is less expansive then I expected, so any help is appreciated,
