We've released a new firmware that implements read-write CAN endpoints, which we call "one-shot" endpoints. Up till now, endpoints in Tinymovr were able to perform either read or write operations; for a write operation, studio transmitted a regular CAN frame asynchronously, while for a read operation, the client transmitted a RTR frame and awaited the response from the firmware. Thus, for a read-write operation, a total of three frames were required.

One-shot endpoints function as read endpoints, but instead of studio transmitting an RTR frame, it transmits a regular frame containing write data, and waits for a response with read data. Thus, for read-write operations the required number of frames is reduced from three to two. The new endpoints are documented here.

The new firmware is available immediately. Do not forget to update your Studio installation as well!

In addition, we have released Dianome (/ðʝanoˈmi/, from the Greek word διανομή, meaning "distribution"), a compact power distribution board with protection features. Dianome allow distribution from a single male XT-60 connector to six XT-30 female connectors. It has inrush current limiting, and as such can be used to drive large capacitive loads in the range of several 1000 μF. In addition, it has over- and under-voltage and short protection. It has a footprint of 32 x 32mm and standard hole spacing of 30,5 x 30,5mm.

Dianome is currently in beta, which means there will probably be rough edges and you will have to solder the connectors yourself. We are working on improving these aspects. On the up side, you get the board (and connectors if you choose) at a favorable pricing.
