| contents | PIC32-Based Scheme for Signaling and Transferring Images From an FFT-CCD Sensor Through USB A. Serrano J.C. Vélez M. Calle Ingeniería CCD USB control acquisition Full frame transfer The paper presents important design characteristics of the control scheme for an FFT-CCD sensor. The hardware module employs a microchip PIC32 core with a Hamamatsu CCD sensor, for image retrieval, conversion and transfer to a computer. The paper focuses on describing the core programming for sensor control and USB communication. The description provides useful information for researchers and hardware interface developers. The system was tested for transfer delay in USB connections with different number of endpoints and three endpoint sizes. Results show that USB connections with three endpoints and 64-byte endpoint size have the smallest transfer delay, 1 second. Connections with two endpoints increase delay in 100 milliseconds; however, this setup is simpler to implement. 2012 artículo científico 1665-6423 https://www.redalyc.org/articulo.oa?id=47425142008 en http://www.redalyc.org/revista.oa?id=474 Journal of Applied Research and Technology application/pdf Universidad Nacional Autónoma de México Journal of Applied Research and Technology (México) Num.6 Vol.10 |
