The dacHandler piggyback board arrived and I immediately machined a hole for the reset switch, but the positioning is delicate, interfering with the X’tal at the very last minute. A jig for writing data to FPGA was fabricated. Then, the firmware was written to the FPGA. Initially, the writing failed because I had forgotten that
Unfortunately, the width of the Trill Flex sensor protrudes from the base. I will have to manufacture the exterior using channel material of the width of the sensor to cover the base, but it seems difficult to obtain channel material with an inside diameter of 20 mm exactly. There is a way to procure a 1-inch wide
The i2c is received by ESP32S3, and the output is output to the main body of the instrument via ESP-NOW. An illuminated push-switch was installed, but it took a lot of time and effort to drill the holes in the stainless steel. The touch sensor and its control board will be mounted bare on the
The dacHandler is a system developed to communicate with audio DACs without using the I2S built into the MCU. The format of the data to be handled can be changed by the output destination DMA. The format of the data handled depends on the destination DAC, so it is necessary to convert the audio data
