We use an Infineon FP 420 L 90 B magneto-resitive sensor to sense position in a precision tilt mechanism, but Infineon no longer makes this part. Does anyone know of a replacement part made by Infineon or another vendor that could take the place of this device?
Show LessHi, I am using Aurix TC375 Lite Kit development board and tried the freeRtos example code.
But after compilation, once the code is put in the debugger mode then the tsim issue comes as below snapshot --
Please get me a solution for this issue asap.
Thanks.
Show LessIs it possible to edit the RIC7S113 spice model so it will run on LTspice?
I am running bldc motor with the help of hall sensor but not able to get full no load speed.This motor has 1000 rpm but getting only upto 3500 rpm.
I am using example code to drive this motor whether this code support 10000 rmp.
My motor is working at 48v,750 W.Could you help to resolve this problem
Show LessWe currently have an application which streams a 720x720 video stream at 30fps in YUV format (2 bytes per pixel). We are using a USB high speed interface (no superspeed available), which is close to the practical limit of this stream. Occasionally, we get error 71 (CY_U3P_ERROR_INVALID_SEQUENCE) from CyU3PDmaMultiChannelCommitBuffer. It seems like this happens if the USB bus is busy due to high load. If this happens, I would like to drop the current frame, by resetting the GPIF state machine and not send any more packets for the current frame. This is my code:
void cameraDmaCallback(
CyU3PDmaMultiChannel* chHandle,
CyU3PDmaCbType_t type,
CyU3PDmaCBInput_t* input)
{
(void)input;
CyU3PDmaBuffer_t DmaBuffer;
CyU3PReturnStatus_t status = CY_U3P_SUCCESS;
if (type == CY_U3P_DMA_CB_PROD_EVENT)
{
if (sIsStartOfFrame)
{
sDmaDoneCount = 0;
}
status =
CyU3PDmaMultiChannelGetBuffer(chHandle, &DmaBuffer, CYU3P_NO_WAIT);
while (status == CY_U3P_SUCCESS)
{
/* Add Headers*/
if (DmaBuffer.count < sUvcDataBufferSize)
{
uvcAddHeader(
(DmaBuffer.buffer - ES_UVC_PROD_HEADER), ES_UVC_HEADER_EOF);
sHitFv = CyTrue;
}
else
{
uvcAddHeader(
(DmaBuffer.buffer - ES_UVC_PROD_HEADER),
ES_UVC_HEADER_FRAME);
}
/* Commit Buffer to USB*/
status = CyU3PDmaMultiChannelCommitBuffer(
chHandle, (DmaBuffer.count + 12), 0);
if (status != CY_U3P_SUCCESS)
{
sIsStartOfFrame = CyTrue;
sHitFv = CyFalse;
sActiveSocket ^= 1;
if (sActiveSocket)
{
CyU3PGpifSMSwitch(
ES_UVC_INVALID_GPIF_STATE,
CX3_START_SCK1,
ES_UVC_INVALID_GPIF_STATE,
ALPHA_CX3_START_SCK1,
ES_UVC_GPIF_SWITCH_TIMEOUT);
}
else
{
CyU3PGpifSMSwitch(
ES_UVC_INVALID_GPIF_STATE,
CX3_START_SCK0,
ES_UVC_INVALID_GPIF_STATE,
ALPHA_CX3_START_SCK0,
ES_UVC_GPIF_SWITCH_TIMEOUT);
}
CyU3PEventSet(
&sUsbCameraEvent, USB_COMMIT_FAIL_EVENT_FLAG, CYU3P_EVENT_OR);
return;
}
sIsStartOfFrame = CyFalse;
sDmaDoneCount++;
sActiveSocket ^= 1; /* Toggle the Active Socket */
status = CyU3PDmaMultiChannelGetBuffer(
chHandle, &DmaBuffer, CYU3P_NO_WAIT);
}
}
else if (type == CY_U3P_DMA_CB_CONS_EVENT)
{
sDmaDoneCount--;
// Frame done
if ((sHitFv == CyTrue) && (sDmaDoneCount == 0))
{
sHitFv = CyFalse;
sIsStartOfFrame = CyTrue;
if (sActiveSocket)
{
CyU3PGpifSMSwitch(
ES_UVC_INVALID_GPIF_STATE,
CX3_START_SCK1,
ES_UVC_INVALID_GPIF_STATE,
ALPHA_CX3_START_SCK1,
ES_UVC_GPIF_SWITCH_TIMEOUT);
}
else
{
CyU3PGpifSMSwitch(
ES_UVC_INVALID_GPIF_STATE,
CX3_START_SCK0,
ES_UVC_INVALID_GPIF_STATE,
ALPHA_CX3_START_SCK0,
ES_UVC_GPIF_SWITCH_TIMEOUT);
}
}
}
}
This seems to work sometimes, but not all of the time. In the times that it doesn't work, the end of frame seems to never happen. Are there additional things I need to do to restart at the next start of frame, either related to the GPIF, or the DMA?
Show LessI am reviewing an old design for a spectral lamp power supply. Spectral lamps are a type of arc lamp that are rated 10W to 60W at 1A, made by Osram. The power supply, is traditionally 50Hz mains choke and a florescent tube starter. Spectral lamps do not have a heater but start with a voltage of less than 1,500V briefly, then run at high voltage vaporising a metal or causing a gas to ionise flouress.
I developed a switch mode power supply 30 years ago which ran well the lamps' life went way beyond what was expected of it and the quality of the light was much better because there was virtually no flicker, so it was used with electronic devices. But the transistor and inductor losses were higher than would be possible now with a zero current or zero voltage switching controller. There was no power factor correction, and the power supply only operated with 230Vac, though it would run at much lower voltage with the lower power lamps.
XDPS2201 seems to run with a variable PWM and current mode, similarly to the circuit I have drafted on my blog. I believe this part would run similarly to UC3806 in my blog.

I am also considering high frequency fluorescent tube ballast's and using variable frequency for lamp current regulation. I have drafted a design using chokes rather than chokes and a transformer. The arc would be struck with L1 C12 at about 28KHz. Then run at 128KHz or higher when L2 C12 resonate. I have not worked these out properly, but the circuit could output a higher voltage than the incoming voltage, which I have modelled a little on the blog.

My question is am I on the right track by considering this controller?

I am now using the ESP32 to stream the raw radar data from XENSIV™ BGT60TR13C radar wing board (SP005568071) through UDP. For each chirp in the radar setting, I have 128 ADC samples. But I found that there was always a noise at a fixed frequency as shown in the attached figure. I tried to change the sampling frequency but this noise was still there. Do you know what caused this issue?
Thank you!
