General Discussion / Serial line noise
May 31, 2018, 04:55:49 PM
On the TinyScreen+, I have it connected to the terminal block breakout. I am using lines 0 and 1 for Serial communication. However, I am experiencing a lot of noise on this. The lines are extremely short and I haven't had this kind of issues in the past with other Arduino hardware.

I do not have any other boards connected. Are there some issues on these pins that I should be aware of?

General Discussion / Can't read battery voltage
May 31, 2018, 04:54:14 PM
I have a TinyScreen+

I am reading the ADC line A4 (thats what appears to be wired up in the schematic), but I am getting a bunch of random values.

Is there any particular trick to obtaining the voltage?

Has anyone played with BG Script on the BLE112?

The BGLib example is compiling in at 13kB, not to mention with some significant complexity.

The idea is simple: offload as much functionality as possible onto the BLE112 and run it in stand alone mode. Create a very simple UART control interface for transmitting and receiving data.

Before I start, has anyone already done this?

I did something very similar with the Telit GSM module (Python variant), and I was able to quickly hammer out new sketches without having to bother with all of the overhead.

Any idea when GPS or WiFi modules will be back in stock?
