Trouble connecting to module through sigma studio
Hello, We are attempting to use Sigma studio and ADUSB2EBZ USB adapter in order to debug our custom board but we are having a problem where we often get a "Compiled Comms Failed" issue when attempting

LED Control
Hello, In the digital output section in the datasheet it says that those pins are not designed for draw static current. But: - Could it control several LEDs (one LED per pin) with 1mA if the maximum i

GPIO LED control
Hello! My task is to turn on one LED when one position is selected on the switch and turn on another LED if the second position is selected. Surely, this simple task has already been discussed, but I

How to use 1452 or 1701 make a signal level detector to make LED has different brightness while signal strength change?
Hi, I want to use 1701 and 1452 to make a level detector to detect the signal strength, but I don't know how to use blocks to make led brightness will follow the signal strength. The led brightness le

E2PROM: FAILED TO WRITE / ADAU1452
Hello, we have a sporadic problem with an ADAU1452 processor that is configured in selfbootmode with a Microchip 24AA512 EEPROM (http://ww1.microchip.com/downloads/en/devicedoc/21754m.pdf). When we wr

Sigmastudio comm failed with BF706 ezkit
I have the Adsp-BF07 ezkit and used it successfully in the past with Sigmastudio. I haven't used it in about 2yrs and since then most of my computers are now upgraded to Windows 10. My projects compil

USBi comm error with Windows 10
My Win 10 laptop is no longer on speaking terms with my USBi / eval boards, resulting in Comm errors and nonworking readbacks.. My work computer worked fine until as an experiment I deleted its USBi d

Limiter indicator led
Hi, I am looking for a very low instruction usage setup which can switch on a led when the treshold of a limiter is reached. I have this setup: But the signal detection block, stays on too long as the

[Bug Report] Data Controlled Asymmetric Clip
Title: Data Controlled Asymmetric Clip threshold clipping issue Description: The negative side of the sinewave is hard clipped at -1.0 even if Clip Down pin is set at -0.4 value. The positive side is

Need to expand SigmaStudio State C beyond 9999999 bytes
Hello, We are developing a product using SigmaStudio 3.12 for SHARC and the 21489 DSP. We are planning on using an external SD RAM (512MB) for a pooled audio delay. Here is an earlier thread: Running

External LED Array Driver block?
I would like to use an external LED array to show the in- and output level in my dsp project (ADAU1701). I found an intresting block in the sigma studio wiki (External LED Array Driver) but it says "T

Will there be a Voltage Controlled Delay for ADAU1452 DM0 and DM1 available ?
Hi Analog, I often work with the Multitap Voltage Controlled Delay Block. In the ADAU1452 there are now 3 types of delay available: DM0, DM1, External SPI. Only one of them is available as voltage con

PWM clip LED
Hi I'm trying to implement a clip led on the 1701mini dev board. I found the following threadMonitoring average and instantaneous signal levels which works but it's an instant on/off led. I'd prefer s

Why does the blinking led example in AN-951 not work?
I am trying to get some custom hardware up and running and the blinking led example does not work. I can manually toggle the output pins by using the read/write registers tool but I cannot generate th

Problems with multiply - AD1940 on SigmaStudio
I'm using two sources, one DC with 28.0 and a sine tone, then multiplying it and using the real time display (in 28.0 format) to see the result. The negative numbers are represented as the maximum pos

Use of an ADAU1761's input to control VCDelay
Hello, I have an EVAL-ADAU1761Z and SigmaStudio. I wish to control the value of a VCDelay (from 0ms to 80ms) with an external signal. How can I do ? I thought about using an ADC input and an external

no communication from host pc and 21489 board on sigma studio
Hi I just received the ADSP-21489 EZKITLITE and am starting to work on it. When I connect the USBi block to the ADSP-214xx block in hardware configuration, the USB color is always red and it should be

LEDs pwm gpio
I have a status LED on two of the GPIO pins. Is there a way to pulse width modulate the blinking of the LEDs? I can turn them on and off ok. And I think I was successful in getting the LED to blink wi
