I was trying to display my I2C acelerometer (x) value on the console using Meowbit. It works fine in the simulator ([https://arcade.makecode.com/beta#editor](https://arcade.makecode.com/beta#editor)) but the code won’t compile so I cannot download the uf2 file. ![arcade-test_accel](https://us1.discourse-cdn.com/flex020/uploads/makecode/original/1X/e767e7d76f97e66afcacc6a8639fbea560f7b099.png) What am I missing here? ---

In `beta beta` I get a `Compilated failed, please check your code for errors` for Meowbit target. Is that what you get? The first one took a long time, maybe a minute to appear. It then becomes near-instant if I hit Download again. `built/output.txt` isn’t helpful, it says, `Everything sems fine!`. I switched board to the PyGamer target. It took a long time again but did work, downloaded ok to the device and tests fine. For me it appears not to like the Meowbit. ---

Here’s what I found: It did not compile with Makecode Arcade BETA but it worked just fine with Makecode Arcade. ---

Hm, thanks for pointing this out, filed here: [https://github.com/microsoft/pxt-arcade/issues/1406](https://github.com/microsoft/pxt-arcade/issues/1406) ---

Referencing a similar post below: [https://forum.makecode.com/t/re-d51-sound-mixer/735](https://forum.makecode.com/t/re-d51-sound-mixer/735) But my LIS3DH has a default address at **0x18**. Does that mean I have to set the config to this value when compiling the bootloader? 1, 0x36, // PIN\_ACCELEROMETER\_INT = PB22 2, 0xd, // PIN\_ACCELEROMETER\_SCL = PA13 3, 0xc, // PIN\_ACCELEROMETER\_SDA = PA12 70, **0x18** , // ACCELEROMETER\_TYPE = LIS3DH How do I set/change the LIS3DH address on the patcher? ---

There is a bit of confusion around i2c addresses being 7 or 8 bit. 0x18\<\<1==0x30 so I suspect you need 0x30. 0x18 will not work. ---

Thank you @mmoskal. I used LIS3DH\_ALT on the patcher and it worked like a charm. 🤗 ---

Hi there, I am trying to make a LIS3DH work as well, but with a Trinket M0. The LIS3DH is connected to the SDA and SCL pins of the Trinket, but I get the reading 0 for all the axis. I tried with SDO connected to 3.3V and unconnected, but it doesn’t change. Is there anything I can try to make this work? Cheers, David ---

So, I went through “accelhw.cpp” and found that it should just work, if there are sda and scl pins with a LIS3DH connected. Nevertheless I tried to set the variables in the config like 204maker mentioned. In “main.ts” I wrote: ```auto namespace config{ export const ACCELEROMETER_TYPE = DAL.ACCELEROMETER_TYPE_LIS3DH_ALT; export const PIN_ACCELEROMETER_SDA = DAL.PA08; export const PIN_ACCELEROMETER_SCL = DAL.PA09; export const PIN_ACCELEROMETER_INT = DAL.PA02; } ``` Now the binary.asm says: ```auto .word 1, 2 ; PIN_ACCELEROMETER_INT=2 .word 2, 9 ; PIN_ACCELEROMETER_SCL=9 .word 3, 8 ; PIN_ACCELEROMETER_SDA=8 ... .word 70, 48 ; ACCELEROMETER_TYPE=48 ``` But now the Trinket hangs completely and I even don’t get the 0 reading. Is there a way to debug this?
