I can see an old list of known-good USB dongles. I'm looking for a known good BT5.0 dongle, but the ones in the list are listed as not working. Is there an updated list?
I added a 10 millisecond delay and it it helped. I now see the full file play the first time and no static. The second attempt still does nothing. The third is not reached. I get nothing on channel 1.
I formatted the SD card and tried one of the files posted and it did almost the same thing. This time, the file quits playing after a fraction of a second, then garbage for a second or two. (The file is over a minute...
I'm making a soundboard that plays a file via the onboard DACs, but WAV playback from the SD card is behaving very strangely.
I have full code below, edited down to a simple test of playing one file. When I run the...
I have a setup where I am sending camera data over UDP that was working yesterday. Today I am seeing strange behavior:
1. My first attempt to compile threw a bunch of weird errors. I closed the IDE and retried and...
My goal is to stream IMU data to a PC over BLE. I have a T4.1 on a board with the USB host port set up. I'm hoping to get a pair of USB dongles to complete the link.
I can see a thread with a list of tested dongles,...
I completed a USB keyboard pass-through where a T4.1 translates the keystrokes from a one-handed gaming keyboard to enable full one-handed typing. I'm now sucked down the custom-keyboard rabbit-hole and I want one.
...
I'm using a Teensy 4.1 as a pass-through on a one-handed gaming keyboard to implement full single-handed typing and improve cursor navigation and access to It's working great and I'm getting used to it quickly, but...
I'm going through the OV7670 libraries and at first pass I can't find pin assignments. It seems these libraries are using the 'CMOS sensor interface'. I think I need to read about that first. I can't find much via...
Thanks. I'm using a T4.1, so it looks like I can use an OV7670 without cost issues.
It looks like the libraries were last worked on last year. Were they left in a mature state?
I'm using an Arducam 5642 and got burned: Although I can get each frame quickly over SPI, the camera takes forever to make the data available, so I get a frame rate of about 2 seconds.
I have the UDP JPG datapath...
I want to be able to type efficiently with one hand. I have a left-handed gaming keyboard with extra buttons accessible to the pinky and thumb that can easily be used as SHIFT\ALT\CTRL modifier keys. I want to use my...
Yes the Teensy needs to do other things while the SPI is taking place. I was not aware of the approach above using eventresponder. This is really all I think I need. However, can you confirm efficiency of this method...
It was a typo mentioning QSPI...I meant PSRAM chips for memory...QSPI was a different message that day:(
Regarding memory, I have the external memory stuff working via the EXTMEM command. As you say above, I need a...
I have a use case where I need to receive camera data via SPI and re-transmit it via UDP over ethernet. I'm hitting performance issues and need to use more advanced features to improve throughput and latency.
At...
I have a Teensy 4.1 application where a known number of SPI reads take place sequentially. I want to ferry the data from the SPI reads to a RAM buffer implemented with the auxiliary PSRAM chips. It seems like others...
Wow thanks! Great news that there may not be anything wrong with the boards.
I'll take another lap though the libraries and retry.
Does Teensy make any electrical checks on the port when initializing?
I got a T41 breakout PCB made that has an RJ-45 header and needed capacitor configured. I'm having several issues:
1. Without the Teensy attached, I am observing T+, T-, R+ and R- all shorted together. It's likely I...
UART I\O IS an option. What's available?
Both the units you listed require I2C. The ADCL343 clearly shows I2C. The BNO080 requires it to setup the SPI:)
I had the idea of setting up an interrupt on the SPI clock so...
